Seems like they just ran a blanket scrip that gave every player 750 points, regardless if they already received the points or not. There has to be some way to determine if a player originally received his points. I'm not sure how they can go back and check unless they store that information in the database. If so, it would be easy to just not give those players 750 points after the next game. You can't take points away because some players have already spent them.
